LOOM-SHUTTLEa SPECIFICATION forming part of Letters Patent No. 400,152, dated March 26, 1889.

Application filed May 4, 1888. $erial No. 272,844. (No model.)

To aZZ whom it may concern:

Be it known that we, CHESTER F. WIOKWIRE and THEODORE H. WIOKWIRE, of Cortland, in the county of Cortland, in the State of New 5 York, have invented new and useful Improvements in Loom-Shuttles, of which the following, taken in connection with the accompanying drawings, is a full, clean-and exact description.

This invention, although applicable to some extent to nearly all kinds of shuttles, is more especially designed for shuttles employed in looms for weaving wire-cloth.

In the operation of the shuttle the pivoted spool receives such a momentum of rotation during the passage of the shuttle across the loom that at the end of each passage the spool continues to rotate sufficiently to cause some of the wire to become unwound therefrom and entangled'or snarled, and thus interfere with the operation of the shuttle. Attempts have been made to overcome this defect by a friction-brake bearing on the periphery of the spool; but in practice it is found that such an arrangement of the brake causes the latter to produce wear and abrasion on the spool, and inasmuch as the leverage to overcome the resistance of the brake is reduced with the reduction of the circumference of the wire on the spool during the operation of the shuttle the strain upon the wire running from the spool frequently becomes so increased as to cause the wire to break.

Our invention consists, first, in the employment, in combination with the shuttle and its spool, of a friction brake-band trailed in the shuttle by the rotation of the spool, which brake-band retards the rotation of the spool and produces sufficient recoil of the spool at the ends of its thrusts to quickly take up any slack of the wire that may occur; and the invention also consists in a novel construction of the shuttle specially adapted for the aforesaid improved friction-brake of the spool, all as hereinafter fully described, and specifically set forth in the claims.

In the annexed drawings, Figure 1 is a plan View of our improved shuttle. Fig. 2 is a side view of the same. Fig. 3 is a plan view of the shuttle, minus the spool, and a portion of the plate covering the brake broken The shuttle is formed with the annular central portion, A, and elongated end portions, A A and has rigidly attached to the center of the central portion, A, the spindle Z), on which is placed the spool D. The spool is retained on the spindle by a suitable keeper, I, placed across the free end of the spindle. To facilitate the attachment and removal of the spool,we prefer to form the keeper of a bar hinged at one end to one of the end portions of the shuttle and detachably connected to the other end portion of the shuttle, and make the connection of said parts by providing the end portions, A and A, of the shuttle, respectively, with grooves a and a, and forming the aforesaid bar with a perforated car, 01, which enters the groove a, a pin passing transversely through the shuttle portion A and through the aforesaid ear. The opposite or free end of the bar terminates with a lug, j, which enters the groove to, and is provided with a notch, 02. In this latter groove is arranged a spring-actuated bolt, 0, which is adapted to engage the notch n, and thus lock the bar or keeper I in its position across the free end of the spindle.

The shuttle is provided with an annular case or recess, 1', concentric with the pivot of the spindle, and in this case is seated our improved friction-brake, which consists, essentially, of a band of suitable material trailed in the case by the rotation of the bobbin, and which is susceptible of many modifications. \Ve, however, prefer to employ a coil-spring, f, connected at its inner end with the spool by the instrumentality of a collar, (Z, at the base of the spindle b, and having the aforesaid end of the coil-spring suitably connected to it and provided with suitable means for engaging the spool, so as to rotate with it, said means being represented in the form of lugs e e, projecting from the collar and entering sockets Z l in the adjacent side of the spool. Said coil-spring is confined in the case or re- IOO cess r by a plate, l1,covering the spring and detaehably connected to the shuttle by screws ft or other suitable means. The spool is ap plied to the shuttle by raising the free end of the keeper I from the shuttle, then slipping the spool on the spindle, and then placing the keeper across the spindle and locking it by the spri n g-actuated bolt 1'.

In the operationv of the shuttle the rotation of the spool first partly winds up the coilsgringf and then drags the same, and in do ing so the dragging end thereof isin frictional contact with the periphery of the interior of the case or recess '1', and thus prevents the spool from receivingunduemomentum. \Vhen the shuttle is arrested in its movement, the partially-wtiund-up spring f causes the spool to recoil sutlicieutly to ga'tther up any slack that may be produced in the wire running from the spool, and thus the entanglen'lentot the Wire is effectually obviated.

\Vhat we claim as our invention is l. The combination, with the shuttle-body provided with an annular case and a rigidlyattached central. spindle, of a collar loose on the spindle and adapted to engage and rotate with the spool, a coil-spring connected to said collar and trailing in the ease, and a keeper placed removably across the free end of the spindle, substantially as specified.

J. The combination, with the shuttle-body having an annular case and a central spindle rigirfllysecurod to said body, of a collar loosely mounted on said spindle and adapted to engage and rotate with the spool, a coil-spring connected to said collar and trailing in the annular case, and a keeper reaching across the spool and the free end of the spindle, said keeper hinged at one end to the shuttle-body and the other end engaging a catch 011 the other end oi the shuttle-laid substantially as specified.

.3. The combination of the shuttle-body formed with an annular central portion, A, elongated end portions, each of which is provided with a groove, the spindle I), the keeper I, hinged in the groove CL, and having its free end provided with a notch, n, and the springactnated bolt 0, adapted to engage the notch on the keeper, substantially as specified.

4C. The combination, with the shuttle-body having an annular case and a rigidly-attached central spindle, of a keeper extending across the spool and free end of the spindle, one end of said keeper hinged in a groove formed in the shuttle-body and the other end provided with a notch, n, and a springactuated bolt adapted to engage the notch n, substantially as specified.

5. The WilJlllIl-(lGSCl'lbOCl shuttle, formed with the annular central. portion, A, annular recess 1', and elongated end portions,A A, having, respectively, grooves (t a, the spindle Z), the collard, mounted on said spindle and provided with lugs e c, the spring f, connected at one end to said collar and having its free end trailing in frictional contact with. the periphcry of the recess 7', the plate covering said spring and det'achably connected to the shuttlebody, the keeper I, hinged in the groove CL and extending across the tree end. of the spindle, and provided with a notch, "II, and the spring-actaiated boltlocated in the groove a and adapted to engage the notch 11, all con structed and arranged substantial] y as described and shown.

In testimony whereof we have hereunto signed our names, in the prestaice of two witnesses,at Cortland, in the county of Cortland, in the State ot' New York, this id. day of May, 1888.
